3 Claims.

This invention relates to an agitating apparatus, and it is primarily anobject of the invention to provide an apparatus of this kind intended asan attachment or accessory for a washing machine whereby the power shaftof such washing machine may be readily and conveniently employed as thedriver for the apparatus in making ice cream or churning butter.

It is also an object of the invention to provide an apparatus of thiskind having means whereby the same may be readily and effectivelyengaged with the shaft of a washing machine and also to provide anapparatus including a dasher carrying scraping means.

Another object of the invention is to provide an apparatus of this kindwhich may be readily applied to or removed from working position withoutrequiring any special mechanical skill on the part of the individual.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improvedagitating apparatus whereby certain important advantages are attainedand the device rendered simpler, less expensive and otherwise moreconvenient and advantageous for use, as will be hereinafter more fullyset forth.

The novel features of my invention will hereinafter be denitely claimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:-

Figure 1 is a vertical sectional view taken through an apparatusconstructed in accordance with an embodiment of my invention and isapplied or working position, certain of the parts being in elevation;

Figure 2 is a fragmentary detailed sectional view taken substantially onthe line 2-2 of Figure 1 looking in the direction of the arrows;

Vthereof is an elongated tapered sleeve 3.

desired mounting for direction of the arrows with As disclosed in theaccompanying drawings, T denotes a tub arranged within an outer casingor shell C while L denotes a lid coacting with the upper face of thecasing or shell C. The foregoing are of a character as comprised in aconventional type of washing machine and in their detailed structureform no part of the present invention. This is also true of theupstanding shaft AS positioned substantially axially of the tub T andwhich is adapted to be driven in any desired manner.

The shaft S is adapted to support the agitating members or dollies ofthe washing machine which, however, are removed from the shaft S andfrom within the tube T when my improved apparatus is employed.

My improved apparatus as herein disclosed comprises an outer receptacleA and an inner receptacle B each of desired capacity, the innerreceptacle B however being materially smaller than the outer receptacleA so that when the receptacle B is placed within the receptacle A anintervening space 1 is provided in which ice or other refrigerant mediummay be placed and particularly when it is desired to use the apparatusin the making of ice cream.

Extending upwardly through the bottom wall 2 of the outer receptacle Aat the axial center As clearly illustrated in Figure 1, the lower orlarger end of the sleeve 3 extends below the bottom Wall 2 of the outerreceptacle A and is dened by an outstanding annular ilange 4 having itsperipheral portion 5 angularly disposed for direct contact with thebottom wall 2 of the receptacle A whereby the flange 4 is spaced fromsaid bottom wall 2.

The sleeve 3 and the peripheral portion 5 of the ilange 4 may be welded,soldered or otherwise positively secured to the receptacle A or, ifpreferred, the desired assembly of the sleeve 3 may be maintained byfrictional contact of the sleeve with the edge defining the opening inthe bottom wall 2 of the receptacle A through which said sleeve 3 isdirected. The sleeve 3, when the apparatus is in applied or workingposition, surrounds the portion or the shaft S within the tub T whilethe flange 4 has direct Contact with the bottom wall 6 of the tub T andthereby provides the the receptacle A. 'I'his flange 4, as particularlyillustrated in Figure 3, is provided therearound with a series ofcircumferentially spaced openings 7 which serve to facilitate the flangeagainst tendency to is in use.

Nesting from above upon the sleeve 3 is a second tapered sleeve 8extending upwardly from the bottom wall 9 of the inner receptacle B. Thesleeve 8 freely engages the sleeve 3 so that the rotate when theapparatus 4 holding the receptacle A receptacle B may be readiLv andconveniently applied within or removed from the receptacle A.

'Ihe lower portion of the receptacle B preferably at diametricallyopposed points is provided with the outstanding radial pins 10, each oiwhich engages from belowthe downwardly facing hook member 11 extendingup from the bottom wall 2 of the receptacle A.

Surrounding the lower portion of the sleeve 3 and interposed between thebottom wall 9 of the receptacle B and the bottom wall of the receptacleA is an expansible coil spring 12 of desired tension and which operatesto positively urge the receptacle B upwardly to assure the eifectiveengagement of each of the pins 10 with its hook member 11. The spring12, however, may be readily compressed by proper stress upon thereceptacle B to allow each of the pins 10 to be engaged from its hookmember l1. It is believed to be obvious that in engaging the pins 10with the hook members 11 or vice versa partial rotation is given to theinner receptacle B.

While in Figure 1 the sleeve 8 is illustrated as being snugly engagedupon the sleeve 3 it is to be stated that there is normally sufficientplay between these sleeves 8 and 3 to allow for the desired engagementor disengagement of the pins l0 with respect to the hook members 11.

Positioned within the inner receptacle B is a dasher D. As hereindisclosed this dasher comprises a frame rectangular in form having theelongated side members 14, a top cross member l5' and a lower crossmember 16. The central part of the upper cross member 15 is formed toprovide a collar 17 having an irregular bore to conform to the upper endportion of the shaft S whereby the dasher D may be keyed to said shaft Sfor rotation therewith.

The central portion of the lower cross member 16 is formed to provide asplit ring 18 which surrounds the lower portion of the sleeve 8 toassure the proper mounting of the dasher D. This split ring 18 issufficiently loose, however, to offer no hinderance or obstruction tothe desired rotation of the dasher D within the receptacle B.

The side members 14 of the dasher D are provided therealong with theinwardly disposed spaced paddles 19, said paddles as particularlyillustrated in Figure 5 being disposed transversely on a desired inclinein order to assure the maximum efficiency of such paddles in agitatingmaterial within the inner receptacle B.

The opposite end portions of each of the rside members 14 of the dasherframe are provided with the transversely disposed slots 20 through eachof which is directed from within a headed shank 21, the outer extremityof which being engaged within an end portion of a scraping member 22.This member 22 as herein disclosed is triangular in cross section withits apex inwardly disposed. By providing a transversely disposed slotthrough which each of the Shanks 21 passes, it is believed to beapparent that irrespective of the direction of rotation of the dasher Da longitudinal edge a of the scraping member 22 will have desiredeffective contact with the inner face ofl the side wall of thereceptacle B. To assure the proper placement of the scraping member 22each of the Shanks 21 has mounted thereon a spacing sleeve 23 of desiredlength and positioned between the side member 14 of the dasher D and theblade 22.

When the apparatus is in assembly and in applied position a guard cap'24 is disposed over the upper end of the shaft S and the applied collar17, the side wall of the cap being slotted, as at 25, so that the uppermember 15 of the dasher will oifer no hinderance or obstruction to thedesired application of the cap 24.

From the foregoing it is believed to be clearly understood that when theattachment is in use only the dasherl D rotates. The receptacles A and Bare held against relative rotation by their interlocking means ascomprised in the pins 10 and hook members 11 while rotation of theapplied containerA is prevented by the bolt heads 7' or kindred elementsextending above the bottom 6 of the tub T and which are received withinthe openings 7 of the flange 4.

The container A is provided in its side wall adjacent its upper end withan overilow opening 26.

From the foregoing description it is thought to be obvious that anagitating apparatus constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principles and spirit thereofand for this reason I do not wish to be understood as limiting myself tothe precise arrangement and formation of the several parts herein shownin carrying out my invention in practice except as hereinafter claimed.
